MEANSVFOR RAISING LOWERING WINDOWS.

SPECIFICATION forming part of Letters atent No. 652,394, dated June `26,1900.

l Application iiled November 7,1899. Serial No. 736,1 S7. (No model.)

To all wtont t may concern:

Be it known that I, ALBERT LAGUS, a citi zen of the Empire ofAustria-Hungary, residing at Prague-Karolinenthal, in the Kingdom ofBohemia, Austria-I-Iungary, have invented certain new and usefulImproved Means for Raising or Lowering Windows and the Like, of whichthe following is a specification.

The present invention relates to a contrivance tor raising and loweringwindows and the like and is especially adapted in connection with thesliding windows of carriages. For this purpose a lazy-tongs deviceconnected with the window-frame is so arranged upon or within the loweror covered part ofthe door that it can be extended orcontracted at willby turning or moving an operating part or handle suitably arranged onthe inner side of the door and within easy reach of the hand of theoccupant, by which means the window may be raised or lowered.

The invention is illustrated, by way of example, as applied to acarriage-door.

Figure l is an elevation of the device, the outer or protecting portionof the door being removed. Fig. 2 is a transverse longitudinal sectionthrough the carriage-door, and Fig.

, 3 represents a detail of the operating mechanism. Figs. 4 and 5 arerespectively a sectional and a front view relating to the stops forholding the win dow at different elevations.

In a groove a of the bottom bar b of the window-frame c are arrangedplates c, connected to the two top members of a lazy-tongs s, and incontact with and running on the under side of said barb are rollers cl,connected to said members and intended to facilitate the movement of thelazy-tongs. The lazytongs are arranged between the double boarding ofthe carriage-door, and the two bottom members are also provided withrollers d', running on a rail or guide f.

The pin g, connecting the two hottomvmembers of the lazy-tongs, issecurely connected with or inserted in a vertical bar or plate h,provided with a longitudinal slot i, in which are guided the centralpivot-pins of the lazytongs. This guide-bar passes through the barfandrests at s on an arched or other spring j, the latter constantly tendingto push the guide-bar upward, and with it the lazy- `ton gs s and thewindow-frame o, connected to the latter.

is arranged a crank device m n, which when .turned in one or the otherdirection will raise or lower the window. This crank device is arrangedas follows: The axle m of the crank n passes through the inner board ofthe door,

mental disk o, provided with an eccentricallyfixed pin p. The pin pengages in ahorizontal groove q of a guide-block r, movable verticallyin a recess t, provided for that purpose in the casing a, inclosing theactuatingdisk o, the guide-block r being pivotally connectzed with theguide-bar 71. by means of the pin f.

The device acts in the following manner when, say, the window is to belowered or opened, in which case the handle n will be turned toward theleft, Fig. 3. In this movement the segment-shaped plate o and the pin pparticipate, with the result that the guideblock r is pressed verticallydownward, the latter carrying with it the guide-bar h. In the movementof the guide-bar, however, the lazy-tongs become involved, owing to thepin g connecting the two parts, and thus also the window-frame, whichdescends and occupies the position indicated in dotted lines, Fig. 2.When turning the handle in the opposite direct-ion, the movements of thevarious parts of the mechanism described are reversed, resulting inanupward movement of the window-frame, in which movement it is assistedby the effect of the spring j on the guidebar h.

In order to be able to tix the window at intermediate positions, severalstops or catches dle on the inner part of the door, which stops give waywhen forced by the crank, but otherwise secure the latter, and with itthe window, in the different corresponding positions. This mechanism isshown more particularly in Figs. 4 and 5. On a segmental plate 00, onwhich the crank-handle n is guided, several stops or catches c (three,for example) are arranged in the path of the crank-handle by means ofsuitable plate-springs y. By 'such arrangement the stops fu' will giveway when On the upper end of the guide-barb at 1 Fig. 2, and is securedto the center of a sego are arranged in the path of the crank-han- IOCforce is applied to the crank, and they will be moved into the space ofthe door in the direction of the arrow, Fig. 4. The position 1 of thecrank-handle n shown in Fig. 5 corresponds to the closed position of theWindow. If the crank-handle is moved between the stops 2 and 3, thewindow is opened a third of its stroke. It Will be understood that thestops are only moved by forcing the crankhandle n, but otherwise securethe latter, and with it the Window, in the different correspondin gpositions.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. Apparatus for raising and lowering windows by means of a lazy-tongsdevice operated by a crank-handle, comprising a pin, on a plateconnected to the crank-handle, engaging with a vertically-movableguide-block connected to a vertical guide-bar to which the pivot-pin ofthe two bottom members of the 1azy-tongs is connected, substantially asdescribed.

2. Apparatus for raising and lowering windows comprising a slottedguide-bar, a lazytongs device, the pivot-pin of the two lower members ofwhich is connected thereto, rollers at the extremities of the endmembers of the lazy-tongs, a guide-block on said bar provided with ahorizontal groove, a crank-plate with a pin engaging said groove, and acrankhandle, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

`ALBERT LAGUS.
